ESC 2002: Xecom introduces embedded wireless communications system

Boston, MA – Xecom introduced its embedded wireless communications system with modem connectivity. The radio frequency-based system consists of the XE 900 Smart Transceiver (ST) and the XE 924 Base Access Point (BAP). Together these network elements provide a complete network solution to linking up to eight remote microcontroller-based systems to a central data collection unit which in turn is connected to a telephone land line via a modem. The system operates in the ISM band (902-928 MHz) to link sys-tems for distances of up to 150 feet indoors. Connectivity to a telephone land line is created by the integral Xecom proprietary modem technology. Applications of this system include industrial and process control, game/video arcades, laundromats, vending machines, office equipment, utility meters, access security systems and other cashless transaction, and remote monitoring control and data acquisition applications.

The transceiver consists of a wireless transmitter/receiver and a microcontroller which has been enriched with user customizable flash memory and Xecom proprietary software. Built-in intelligence accepts com-mands from the application host to control the wireless connection. Proprietary software packetizes data, provides error correction, and insures collision avoidance. Features include small size of 2.75- x 1.38- x 0.55-in. and 5-volt power supply. The cost in OEM quantities is $39 and sample units are deliverable from stock.

The BAP integrates a microcontroller, wireless transmitter/receiver, and XE 2420 surface-mountable complete modem into a single 2.75- x 1.38- x 0.55-in. package. Used in conjunction with up to eight STs, it creates a data acquisition connectivity portal to the outside world via a conventional land line. The inte-gral modem comes with FCC Registration for Part 68 Rules. Price in OEM quantities is $59 and sample units are available from stock.

An available development kit is comprised of one development board containing a XE 900 Smart Trans-ceiver, one development board containing a XE 924 Base Access Point, a data sheet, and a user’s guide. The development kit price is $295 and is available from stock.
